Title Page

Chapter 3 – Complete the two essay assignments noted below: (Information Technology and Organizational Learning)

Review the strategic integration section.  Note what strategic integration is and how it ties to the implementation of technology within an organization.

Review the information technology roles and responsibilities section.  Note how IT is divided based on operations and why this is important to understand within an organization.

The above submission should be two -pages in length (one page for each question) and adhere to APA formatting standards.

**Remember the page length does not include the APA cover page or any references**

Part 1

A principal wants to determine if a new ACT preparation program is effective. The data are contained in the schools.sav data file. Open the schools.sav file in SPSS. Use SPSS to determine whether a significant improvement existed between student performance on ACT tests in 1993 (act93) and ACT tests in 1994 (act94). Assume that the same students were involved in 1993 and 1994 testing. (This requires a t-test. Review Chapter 10 of the Green & Salkind text for information on paired t-tests and reporting APA results interpretation and writing.)

Create a report that answers the principal’s question. Write these conclusions in formal APA results format. Include your SPSS output to support your conclusion.

Part 2

A pharmaceutical company wants to determine whether there is a need for a new medication based on the data in the electric.sav file. Specifically, they want to determine whether a person is alive or dead 10 years after a coronary incident and whether that is reflected in a significant difference in the patients’ cholesterol levels (chol58) taken when the event occurred. Use chol58 as a dependent variable and VITAL10 as your independent variable. Complete the following:

• Analyze these conditions to determine whether there is a significant difference between the cholesterol levels (vital10) of those who are alive 10 years later compared to those who died within 10 years.
• Include the SPSS output, which validates your conclusion.
• Write a brief paragraph describing your conclusions.

Refer to Unit 6 in the Green & Salkind text for specific information about SPSS tests and APA results interpretation and writing. Pay attention to the Levene’s test throughout for determining whether the assumption of equal variance was met when you make your final decisions about the analysis.

What conclusion did you reach? Write these conclusions in formal APA results format. Include your SPSS output to support that conclusion.

Part 3

Occasionally, you have 1 independent variable that has 3 or more levels or groups. For a parametric data set, an analysis of variance (ANOVA) is the proper calculation. Use an ANOVA to address the following scenario:

A financial planner is interested in understanding the relationship between the dependent variable of the income level of respondents (rincdol) and the independent variable of their education level (ndegree) from the gss.sav data file. Use SPSS to complete the following:

• Run an ANOVA to determine the overall conclusion.
• Use the Bonferroni correction as a post-hoc analysis to determine the relationship of specific levels of degree level to income.
• Explain the overall conclusions based on the analysis, and describe the relationship(s) between the levels of the degree earned and income.
• Write your conclusion of the findings based upon the output using proper APA formatting.

Submit both the SPSS output file and your Word summary. (Refer to the Green & Salkind section about a one-way ANOVA for information on APA results interpretation and writing.)

In this project assignment, you will create a program with any high-level programming

languages as you prefer (e.g. Java/C++/Python/Go …) to implement a simplified

version of RSA cryptosystems. To complete this project, you may follow the steps

listed below (demonstrated in Java code) to guide yourself through the difficulties .

Step I Key-gen: distinguish a prime number (20 pts)

The generation of RSA’s public/private keys depends on finding two large prime

numbers, thus our program should be able to tell if a given number is a prime number

or not. For simplicity, we define both prime numbers p and q within range 0 < p, q <

10,000,000 so that a 64 bits primitive type (e.g. long in Java) should be sufficient

to handle most arithmetics calculations involved.

Therefore, your first step is to implement a method that takes such a number in range

as input and output a boolean type value to indicate whether it’s a prime number:

Assignment # 3 is a research assignment.

We studied Apache Pig in lecture # 4. You are supposed to do online research and find out one case study where Apache Pig was used to solve a particular problem. I am expecting 4-page write-up. Please provide as much technical details as possible about solution through Apache Pig. Please draw technical diagrams to explain the solution. 

I am expecting maximum one page for business problem and 3 pages of technical solution. I want everyone to do research and provide their own write-up.

Please draw your own diagrams and don’t go more than 4 pages in total.
